Stainless Steel 17-7 PH Flanges are made from precipitation-hardened austenitic stainless steel, striking a perfect balance between strength, hardness, and corrosion resistance. Typically, their chemical makeup includes chromium (16–18%), nickel (6.5–7.75%), and aluminum (0.75–1.5%). These flanges boast impressive tensile strength (up to 1100 MPa), yield strength exceeding 965 MPa, and excellent fatigue resistance. The 17-7 PH alloy retains its mechanical properties even at temperatures up to 600°F (316°C), making it a fantastic choice for high-stress environments. Additionally, these flanges experience minimal distortion during heat treatment and maintain good formability and weldability post-hardening, ensuring dependable performance under various load conditions.
